Uh, ESC motor-connectors?
So I bought 4 new ESCs for my quad. My motors and old ESCs was color-coded for ease of connection but the three connectors to the motor on the ESC are all red. How do I figure out which ESC-cable to connect to what motor-cable? The ESC is a Turnigy Plush 10A.

Doesn't matter. Connect them up. If the motor doesn't spin the direction you want, swap any two.

Just hook em up, spool up the motor and see in which direction it spins. Do this without a propeller. If it spins the wrong way, reverse two wires. Easy!

Oh ok, thanks. But why is there 3 wires? Positive, ground and signal? Negative for reverse spin?

No ground. Just hook the 3 wires up and like above if it spins backwards swap two of the wires to make it spin the other direction.

If you look down at the ESC, the wires, from left to right, Signal (usually with a yellow shrink tube on it), Postive Power (red shrink tube), and then Negative power (black shrink tube).

three phase motors do not have dedicated negatives. all three wires are positive to a (set of) wire winding(s).(poles) each wire of these windings is connected on one side to esc and the other side to either: all three wires are connected to eachother (star configuration) or the end of one pole is connected to the esc wire of the other pole (delta configuration)  changing 2 wires makes the polarization work the other way around. (trying to keep it simple) |
